Can't work virtusertable in FC1

Hi..

Can't work virtual user table(virtusertable of Sendmail) in Fedora Core 1

I configured "virtusertable", "sendmail.cf", "local-host-names  and DNS Sever setting according to sendmail.org/virtual hosting doc.

But, Can't work virtual hosting?

What's wrong in My Configure?

How can I do?

My Configuration

=============================================

"local-host-names"

firstdomain.com

secondomain.com

"virtusertable"

ceo@xxxxxxxxxxxxxxxx <tab> ceoseconddomain

"sendmail.cf"

...

# my name for error messages
DnMAILER-DAEMON

# Mailer table (overriding domains)
Kmailertable hash -o /etc/mail/mailertable.db

# Virtual user table (maps incoming users)
Kvirtuser hash -o /etc/mail/virtusertable.db
